I have a 72 Super Beetle on want to put a new fuel pump do I have to put sealant on the gaskets or could I just put the gaskets the way they are no sealant
Anytime you are working on the motor it is good to use a sealer on the component you are installing. I would recommend that you clean the block, insulator and the fuel pump and make sure all parts are free of old gasket material and sealer. On this part I would not use a silicone sealer. I would use aviation form-a-gasket on all the services.
